Cleaning and removal device

ABSTRACT

This is a device for cleaning and removal of contaminants from various areas in which cleaning is accomplished by a jet of liquid properly contained to avoid splashing and to concentrate the cleaning effect and removal effect, in which a rubber cup is used to contain and assist in cleaning and removal without contamination of adjoining areas.

BACKGROUND OF THE INVENTION 1. Field Of The Invention This invention isin the general field of cleaning devices and particularly pertains to adevice adpatable to clean limited areas by jet action and so arrangedthat overspray and the like are contained within a'very limited,confined area.

2.'Description Of The Prior Art I am acquainted with a great deal of artin this field. The field of cleaning, and particularly cleaning by meansof a jet stream, is an extremely crowded field.

The great requirements for appropriate cleaning within limited andconcentrated areas, and particularly where liquid pressures and/orcorrosive materials may be employed, has led to many developmentsdesigned to eliminate the many problems inherent.

Some of the U.S.= Pats, for example, which might be deemed to be in thegeneral field. are as follows: No. 1,804,874; No. 2,736,906; No.2,086,149; and No. 937,458.

I have examined the foregoing Patents and other devices related to thisfield of endeavor and have come to the conclusion that there was stillthe need of a greatly improved device which could be made quiteeconomically, controlled easily, and used widely. Such a device is theresult of my investigation, development and inventive work, andisrepresented by this Patent Application.

SUMMARY OF THE INVENTION I have now devised a new and unique arrangementby which some certain known devices have been changed, altered, andreconfigured so as to provide a simple, easy to use, and inexpensivedevice for providing an economical, simple and safe jet stream cleaner.

I have accomplished this highly desirable effect, but heretoforeunrecognizable and uneconomical effect, by combining a shielding device,with a built in nozzle adapter, which is easily connected to a commongarden hose.

It is an object of this invention to provide a new and unique jetcleaning device utilizing a flexible and suctionlike shielding devicefor concentrating the action of a jet stream together with a means foreconomically providing such jet stream.

It is a further object of this invention to provide a device asheretofore mentioned, in which by a unique combination, an ordinaryhousehold garden hose may be used for providing a concentrated jetcleaning device.

It is a further object of this invention to provide a device asdescribed above suitable to carry additional fluids other than householdwater fluids.

The foregoing and other objects and advantages of this device will beclear to those skilled in the art, upon reading the following detaileddescription in conjunction with the attached drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a partially broken awayperspective of a preferred embodiment of a device utilizing theprinciples of this invention;

FIG. 2 is an enlarged partial cross section of an alternative device tothat shown in FIG. I; and

FIG. 3 is a partially broken away perspective of the device of FIG. 1 inuse.

DESCRIPTION OF A PREFERRED EMBODIMENT This device as disclosed in FIG. 1is seen to consist of a shielding device 12, which is essentially thesame as a rubber suction cup, having a neck 14, into which is insertedby ,a threaded connection, a nozzle having a handle 20, and which,through principles well-knownin the art, controls the flow of the liquidinto such suction cup from garden hose or the like 30, which isthreadedly connected to the nozzle arrangement.

In FIG. 3 is illustrated the identical item of FIG. 1, in which thenozzle arrangement has been depressed at 20 to allow the introduction ofliquid under high pressure through the intercommunicating liquid passage49, to work upon and ultimately obliterate stains or the like which maybe upon a floor or other area.

In the alternative arrangement shown in FIG. 2, there is shown thegarden hose 130, the handle 120, the shielding arrangement 114, theshield arrangement 112 and the ultimate fluid-dispensive tip 149.

In my previously described Patent Application, 1 had contemplated theuse of a connector to connect items already on the market. In thepresent device, I have shown two alternatives, the alternative shown inFIG. land-FIG. 3, utilizing a standard nozzle, but also utilizing apremolded shielding device having a female thread arrangement so adaptedas to receive the nozzle device. In FIG. 2, there is illustrated ashielding arrangement in which the nozzle itself is molded with theshielding arrangement, by techniques well-known in the art, so as toprovide single connection to a garden hose 130.

In use, the pressure of a fluid or the like is exerted through thenozzle against any stain or the like existing upon a surface or in anintercommunicating aperture of the surface.

By pressing, properly, against the surface ,to be discharge openingwithin said shielding means, and in which said shielding means isnon-detachably affixed to said fluid passage body.

2. The device of claim 1 in which a fluid dispensing tip projects withinsaid shielding means.

3. The device of claim 2 in which said shielding means comprises asuction cup means.

1. A jet cleaning device comprising a housing having first and second fluid containment and passage chambers therein, the first of said chambers being provided adjacent one end with means to connect to a fluid source, and means at its other end adjustably to pass fluid into the second fluid containing and passage chamber, said second fluid passage chamber being provided at its end opposite the adjustable fluid passing means with an enlarged shielding means surrounding a discharge opening within said shielding means, and in which said shielding means is nondetachably affixed to said fluid passage body.
 2. The device of claim 1 in which a fluid dispensing tip projects within said shielding means.
 3. The device of claim 2 in which said shielding means comprises a suction cup means.
